Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Annual figures: Form EIA-861 for 2024, final release. Monthly state figures run to July 2026.

In its Form EIA-861 filing for 2024, Lake Mills Light & Water, a municipal utility, reported 4,124 residential customers in Wisconsin, with a service territory that touches 1 county.

Its average residential price that year was 13.86¢ per kilowatthour, 19% below the Wisconsin average of 17.18¢ and 16% below the US average of 16.48¢. The figure is residential revenue divided by residential sales, so it folds in fixed charges, riders and every rate schedule the utility bills under.

That works out to an average residential bill of $84.12 a month on average use of 607 kWh a month. Across Wisconsin the average bill was $110.87 on 645 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.

EIA's reliability file has no SAIDI or SAIFI entry for it in 2024; smaller respondents and energy-only suppliers are not asked for one.

The average price is up 5.2% on 2019, against up 21.2% for Wisconsin as a whole, and down 1.4% on 2023.
